I had the same idea when I first started but here is why you do not want to convert all of your ctp into ctpm. It is true ctpm earns some ctp tokens, but your ctp tokens that are staked gives your votes more power, and allows you to earn more on your engagement. The ctpm tokens do not give you any voting power. That is why we say Power up your ctp, because it gives you more power in the community, in fact this is correct for most community tokens the more you staked or powered up the more power you have in those communities. :-)
